These locomotives were designed for light passenger work. Sixty-five engines were built at Darlington and they were the smallest engines in the BR range of standard types. They were similar in design to the 46400 LMS Ivatt class of 1946. They had a lower running plate than most of the BR Standard designs, and were fitted with BR3 3,000 gallon tenders.

The 84000 Standard was a tank engine version of the 78000 class design.

 46400 LMS 46400 class introduced in 1946 by Ivatt. Last one built at Swindon in 1953.
 78000 Standard 78000 class introduced in 1952
 84000 small Tank engine version – 84000 class introduced in 1953

The cab of the 78000 class locomotives was reduced from that fitted to the LMS engines to enable it to fit into a universal loading gauge.

Like the LMS predecessor the BR design had a tender cab to enhance crew protection and visibility when running tender-first.

These locomotives were often known by the nickname Mickey Mouse.

The first locomotive to be withdrawn from service was 78015 which was withdrawn from service whilst based at Darlington in November 1963 after a working life of less than ten years. The record for the shortest length of time in service goes to 78053 which was completed Darlington in November 1955 and was withdrawn from service in July 1964 having spent its entire working life based in Scotland.

The 78000 class engines remained in service longer than the Standard 84000 class tank engine version which were all withdrawn by the end of 1964.

Allocation of locomotives in service as at 1st of January.

Accidents and Incidents

BR Standard Class 2 2-6-0 No. 78018, hauling the 4.20am goods train, set out from Kirkby Stephen on the morning of Thursday, 24 February 1955, hauling eight 20-ton wagons of limestone and minerals. At 5am, it became stuck at Bleath Gill near Stainmore Summit which at 1370 feet high was the highest point on any railway line in England until its closure in 1962. The train, along with its crew remained stranded there until 3pm the following Monday, when the first rescue teams arrived hauled by 78019.

The task was an arduous one; winds of 40 mph were blowing across the summit, which coupled with the arctic-like weather conditions to produce a terrible wind chill factor.

Having dug the engine out of the snowdrift during the night, moving the steam locomotive was another difficult task; when a steam train gets becomes stuck in snow, the heat from its boiler melts the snow around it, but as the boiler cools the melted snow refreezes as ice, meaning that the engine is frozen solid. Workmen had to drape paraffin-soaked rags around the moving parts of the engine and set fire to them to thaw the motion.

78051-Dumfries-April 1966.jpg 78051 at Dumfries-April 1966. 78051 spent all of its working life based at Scottish sheds. It was withdrawn from service in November 1966 whilst based at Dumfries.
